Great for learning ways to do quick mental math!
This book really helped me do mental math WAY faster. Some of the tricks weren't so good though, and I already knew better ways to calculate those problems quickly, but a lot of them were very useful and made it so I could mentally calculate things much faster than everyone around me.

I liked the way the book is presented as a series of very short stories and problemas. Every trick is nice, well executed, with a good example and easily explained. The chapters are arranged in a very useful way.

Same author as the last book I read, but I didn't like the format of this at all. The Appendices were my favorite part.
